To cater to consumer’s thirst for unlimited data, mobile network carriers Verizon, T-Mobile, Sprint and AT&T have all come up with their own unlimited data plans. Here's a look at all the plans, to see who offers what.

Karma has announced a new plan for its shareable hotspot that will enable users to have access to unlimited data for $50 per month. Prior to this announcement, users had to pay $14 per gigabyte of data.

Comcast launched its unlimited data option in Atlanta for customers who are willing to pay an additional $35 fee. Comcast claimed that 60 percent of the residents in Atlanta, Nashville and Miami were interested in the deal.

Verizon has agreed to let customers keep their grandfathered unlimited data plans, but not without a good price. Big Red is adding an extra $20 fee to let you use its data network without being throttled.

MVNO Helio has been dead for years, but it's now back in the game with a new parent company and new prepaid plan. For just $29 per month, Helio offers unlimited talk, text and data, but it's not all as good as it sounds.
